BGLLER-BEARING PRESSING ROLLER FOR DRAWING AND SPINNING FRAMES.

Application filed January To all whom it may concern:

Be it known that I, JOHN S. Horns, a citizen of the United States of Ameri and a resident of lVare, in the county of Hampshire and State of Massachusetts, have invented new and Improved Roller-Bearing Pressing Rollers for Drawing and Spinning Frames, of which the following is a description.

My invention relates to drawing and spinning frames and particularly to'the pressing roller thereof.

The general object of my invention is to provide apressing roller for drawing and spinning frames equipped with a roller hearing, whereby to bring about improved results in the action of the pressing roller or pressure roller on the strand of wool, worst-ed, cotton, or other animal or vegetable fibers.

Reference isto be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the invention. 7

Figure 1 is a schematic view showing the assemblage of a drawing frame embodying my improved pressure roller;

Figure 2 is an elevation showing two of the pressure rollers and their associated driving rollers;

Figure 3 is a central longitudinal section taken through the pressure roller;

Figure l is a face view of the pressure roller with the shaft in section as indicated by the line H, Figure 3.

Referring to Figure 1, the numeral 10 indicates a roving spool; 11, 12 an upper and a lower roller between which the strand 13 of wool or the like passes, the upper roller 11 being a pressure roller. Two pairs of intermediate rollers 14 are shown between the rollers of each pair of which the strand passes. The numeral 15 indicates my improved pressure roller between which and a lower roller 16 thest-rand 13 passes, the roller 16 being a driven roller and driving the roller 15 by friction. After passing between the rollers 15, 16, the strand 13 passes through an opening 17 in the frame A to be formed into a cop 18.

In accordance with my invention I provide a pressure roller assemblage in which a plurality of pressure rollers 15 in practice correspond in number with the number of strands 13;v said rollers 15 are roller bear- 17, 1925. Serial N0; 3,123..

ing pressure rollers and each one of the pressure rollers 15 can turn about the axis of the pressure roller shaft 19. The two rollers 16 shown on the drive shaft 20 in association with the rollers15, in Figure 2, drive by friction said rollers 15 but each roller 15 is free to accommodate itself to its work independent of other rollers 15 coaxial therewith. Each roller bearing roller 15 makes with its associated roller 16 an assemblage independent of the other pressure roller and drive roller units, the strands 13 are effectively gripped at all times and tensioned. Qn

the other hand in the usual arrangementin which a single solid pressure roller is employed, the strands 13 are not treated individually since there is liable at all times to be unequal contact of the pressure roller with the various strands so that one is tensions-d to a different degree from the others and indeed it may be that the tension is marked on one strand or a. number of strands and is negligible in others of the strands.

In each roller 15 is a hardened bushing 21 forming with the hardened shaft 19 a raceway for an annular series of hardened roller bearings 22. In practice any approved tension means may be provided, there being a tension rod B shown as partof the assemblage, said rod being connected with a part of the frame A. and having in prac-.

tice spring means, not shown.

In practice collars 23 are provided on the shaft 19 at each side of each pressure roller 15, said collars having set screws 2% and serving to'prevent axial displacement of the pressure rollers along the shaft 19 as well as serving to prevent endwise displacement of the bearingrollers.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of" my invention, I do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claim.

Having thus described my invention, I claim:

Ina pressure roller assemblage for drawing and spinning frames, a pressure roller shaft, a plurality of separate pressure rollers mounted thereon, a drive shaft common to said pressure rollers, hardened bushings in each pressure roller, roller bearings in each pressure roller having direct rolling contact with the pressure roller shaft, said pressure 7 rollers being adapted to turn independent- 1y of each other, and drive rollers on the drive shaft in frictional driving engagement with said pressure rollers; together with fiat collars on the pressure roller shaft at each side of the "latter, and of larger diameter than the bushings, set screws in said collars to bind the same on said shaft, said collars preventing axial displacement of said pressure rollers and serving to retain the bearing rollers against endwise movement and a common tensioning means acting on the pressure roller shaft to apply pressure to all of said rollers.
